Question: TV SET-TOP BOXES The number of television set-top boxes shipped worldwide from the beginning of 2003 until the beginning of 2009 is projected to be
f(t) = -0.05556t3 + 0.262t2 + 17.46t + 63.4 (0 ≤ t ≤ 6)
Million units/year, where t is measured in years, with t = 0 corresponding to 2003. If the projection held true, how many set-top boxes were expected to be shipped from the beginning of 2003 until the beginning of 2009?
